Greenspan was printing lots of money then like the fed is now. That made up money was the capital he talks about, and selling the loans overseas(we all paid in higher prices later.). But 'capital' sounded SO capitalistic unlike 'made up money'. No wonder capitalist is a bad name now, with him using it then.
Sounds like the “American Dream” for homebuilders and lenders, all backed up by bailouts for the foreseeable losses.
